OSTicket maybe?

Cant speak for OP, but amazon sells them

Something like this

What is the wiring itself? Is it like, old 4 pin telephone wiring?

For a very short run like you mentioned, i'd assume it would work, since I've seen some flat fairly short ethernet cables that I don't believe have the twisted pairs inside them, just straight through. If it was a longer run, the twisted pairs inside the cabling are important.

They also sell very thin cat6 cables that might be a better option, something like this

(I saw in another post you're in the UK, not sure if monoprice ships there or if theres another vendor that you could get them from).

Or if the ethernet cabling is already inside the wall going to an RJ45 wall plate, remove the plate and crimp a connector directly onto the cabling?
